The antibody-dependent cell-mediated cytotoxicity (ADCC), also referred to as antibody-dependent cellular cytotoxicity, is a mechanism of cell-mediated immune defense whereby an effector cell of the immune system actively lyses a target cell, whose membrane-surface antigens have been bound by specific antibodies.
